Some friends said that they need to use fluorine-free trivalent chromium blue passivator for their galvanizing production line, but after trying several passivates, the results are not ideal. Some of the color is not blue enough; some passivation color is not uniform, there will be spots; some passivation salt spray effect is very poor, a few hours on the white rust. So is there a more used fluorine-free trivalent chromium blue passivator?
Today we introduce a fluorine-free trivalent chromium blue passivator BZ-215 from Bigely, which gives a uniform blue passivate film with good corrosion resistance. The product features are as follows:
1, It does not contain hexavalent chromium and fluoride, in line with ROHS, ELV regulations, discharged waste water to meet environmental standards.
2, Products after passivation can be bright and uniform, good corrosion resistance of the blue film, and placed not easy to yellow.
3, Good corrosion resistance, the chromium-free formula of BZ-215 can make the workpiece obtain good corrosion resistance, when the thickness of the workpiece is more than 5μm, the GB/T 6461-2002 neutral salt spray test can reach more than 72 hours.
4, Wide operating range, wide pH range, low temperature to room temperature can be operated, long service life of the tank, low operating costs, can save production costs for customers.
Therefore, about fluorine-free trivalent chromium blue passivator, you should choose a practical passivator such as Bigely BZ-215, and the appearance and performance of the product can meet the requirements. If you need to buy fluorine-free trivalent chromium blue passivator, please call Bigely. Guangdong Bigely Technology Co., Ltd. was founded in 2003, 15 years focus on the development and manufacturing of galvanized fluorine-free trivalent chromium blue passivation agent, is a set of research and development, production, sales, service as one of the high-tech enterprises, Bigely fluorine-free trivalent chromium blue passivator is mature and stable, simple maintenance, cost-effective.
